Multifunctional Thermo-Structural Elements for Small Spacecraft via Additive Manufacturing (MFTS)

Completed Technology Project

Project Introduction

Development of multi-density contiguous structural panel elements, referred to as Multi-functional Thermal-Structures, with integral thermal management features via additive manufacturing approaches.

This 3rd fiscal year internally funded development effort enters into development of an approximately 70 cm by 70 cm (full scale) additively manufactured multi-functional thermal structural planar structure as well as design support for a 22 cm diameter structural shell for planetary atmospheric probes. Subscale panel development (20x23cm) will be completed early in FY 18. Direct Metal Laser Sintering (DMLS) of an Al Si Mg alloy has emerged as the leading approach for work in FY 18. Full scale panel two phase thermal characteristics and mechanical properties evaluation will be completed.
